Manufacturing Quality Control of 4-Phenoxyaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750-800 C in a platinum crucible and measuring mass of non-volatile inorganic residue. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of chloride anions on an anion-exchange column with conductivity detection, quantified against calibration standards. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion; measures absorbance of ground-state atoms at element-specific wavelengths. |
| Iron Content | ICP-OES | Inductively coupled plasma optical emission spectroscopy following microwave-assisted acid digestion; detects characteristic atomic emission lines. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually as the temperature range over which solid transforms to liquid under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against specified criteria in natural or standardized lighting. |
| Organic Volatile Impurities | GC-FID | Gas chromatographic separation followed by flame ionization detection; semi-quantitative screening for residual solvents and volatile by-products. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Sulfated Ash | Gravimetric Analysis | Oxidation of organic matter by sulfuric acid treatment followed by incineration at 600-700 C and weighing of residual sulfate ash. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities using HPLC with diode array detection and spectral library matching. |
